Comment(by robe):

 Are you sure you typed POLYGON(EMPTY).  That isn't valid. In fact I get a
 parse error when I try to cast that to a geometry.

 An empty polygon is this:
 {{{

 SELECT ST_IsEmpty('POLYGON EMPTY'::geometry);

 Which gives:
 t
 }}}

 What your bytea resolves to is this:


 {{{
 select st_AsEWKT('01030000000100000000000000'::geometry) As result;

 result
 ------------
 POLYGON(())
 }}}

 Which I'm not quite sure what to call that.
